sAsni MOUNTING FOR REVERSIBLE WINDOWS.

Original application' filed February 19,

My invention relates to swinging-,sash mountings of the ltype Which permit the full or the limited reversal of the sashes. This application has been divided from my Original application Serial No. 10,221, liled in the Patent @nice February 19, 1925, and Which relates more particularly to the combination of a swinging and sliding sash. mounted in a frame by means of a track secured to the 1o frame, and a shoe slidably engaging the track and secured to the sash. The present application on the other hand relates to the support or iiXture per se Which is adapted to the use of mounting k'windows ofthe Swinging and slidable type. h f

described, ,the sash is usuallyi' pivotally connected to shoes which engage in tracks positioned at Opposite Sides of the Window frame opening, and in order that the Sash- Will be iirmly held in its different positions Suitable means are provided for retarding the Inovement of the Shoes relative to the tracks. Such means have usually comprisedv a resilient member cooperating With the shoe and track to frictionally clamp them together, the degrec of resistance to the movement of the shoe depending on the clamping pressure.v lheuy the sash is in an open position, appor- -tion thereof usually extends outwardly from the Window fremd-andas may be readily understood considerable pressure is thus nec-i essary to Vfrictionallyhold the sash against movement, particularly When a Wind of appreciable strength is blowing. It will be obvious, however, that a clamping pressure su'iiicient to frictionally hold the Sash iirm under ordinary conditions usually entails such resistance to the movement of the sash 40 that opening or closino' of the Window may he eifected only with difficulty.r In accordrance With the foregoing, it is an object of my invention to provide a swinging mounting for the sash which Will cause the cash toA be' held in its different' open positions,Withoutrequiring the use offmanually operated falstoni tioned, the employment of a clamping" pressure such as will interfere With the desired In the use of mountmgs of the character ng means, or* entailing, as above men- 1925, Serial No. 10,221.

smoothness and ease of operation of the sash.. .Another object ofthe invention is to pro vide a device of the character described in kwhich the resilient member is of such form 4 specification A .lt is tol he understood that l! ilo-not limit myself to the shovvingmade thexsaid drawings and description, as Inlay adopt variations of the preferred form within the scope of my invention as set forth vin the claims.

Referring to said drawings: Figure 1 is a sectional plan view of a portion-of a Window equipped With-the mounting` of my invention, the sash being indicated in dotted lines and shown in an open position.

-The mounting of myy invent-ion in its 'pres-7 yent form is designed to provide semi-reversihleness of the sash and is illustrated in con on with a window lof the easement type. Each sash is arrangedV to be provided with.v two mountings', one at the top andthe other at the bottom thereof. Ashere shown, each mounting comprises a track which isy air-py site sidesof theV frame Opening v7. The track is formed with a base plate 8 Whichis arranged tosit in and against the head or the sill of the Window frames,l as the` case might be.- Attachment of the track to the rangei'l to be positioned at each of the' oppoframe is preferably effected by means of screws 9 which extend through openings 12 formed in the base plate.

Angularly disposed with respect to the plate is the guide proper, denoted in general 'by the numeral 13, and w iich, as here shown,

comprises a series oit longitudinally aligned guide portions lll formed by tongues punched in and offset from the plate. Each track has associated therewith a shoe 1 6 which is arranged to be moved relative thereto and to be guided in such movement by the guide 1.8.

Pivoted to each shoe, such as by means of pivot bolts 17, is a plate 18. The plates are arranged to extend along opposite stiles 19 of the sash Q1 and adapted to be rigidly secured to the sash. The latter in addition to being pivoted to the shoes, is connected to the trame by links 22 in such manner that reciprocation ot the shoes will cause oscillation oli' the sash, the extent of such movement being here designed to allow the sh to be moved from a fully closed position to one of semi-reversal of vice versa.

'lhe shoe 16 comprises a body 2T and angularly disposed bearing members 28 and Q9 edge of the guide 13.

which are arranged to slide upon the plate at opposite sides of the guide member 13j the body portion 27 being arranged to lie spaced from the plat-e and disposed across the 'free Engagement of the shoe with the guide 13 is preferably effected by' causing the bearing 28 to engage therewith, suoli engagement being maintained. by means of a soring 81 which is fined to the 'shoe and is arranged to bear against the guide. 'lhe spring is positioned to lie between the body member 27 and the base 8, and preferably abuts against the bearing member 29. rlongues 32 assist in holding the spring against the member 29, and co* operation off such tongues with an olset 33 of the spring prevents lateral. displacement of the spring with respect to the shoe. Transverse disengagement of the shoe from the tracl; is prevented by a flange /l termed at an edge of the track. -t will be noted'by reference to Figure L that a comparatively large space is provided between guide 18 and the bearing member 299 and that a spring of relatively large size may thus be interposed between such members. lln this manner the deformation of the spring as a whole may be considerable without imposing appreciable strain thereon. lt will also he noted that positioning oi: the spring in the manner described, permits oi the shoe being both guided by kept in resilient en Y ment with the track by the use et bre single guide member 13.

lt will be clear that owing the spring pressure holding the giiide 13 and bearing 28 in rietional engagementfa the movement or the shoe relative to the tracl will be to a time do not appreciably effect the ease et operation of the sash. ln the present embodiment of the invention such lastmeans is ncorporated with the preceding described means and requires practically no additional parts. As clearly shown in Figure 3 the series of portions l-l comprsing the guide member 1.3- are separated trom each other by spaces 3G, and suitable means are provided on the shoe to automatically engage in or disengage from such spaces upon m'ovemen of the sash, whereby the movement of the sash upon such engagement, will be resisted to a greater degree than that with which its movement is resisted, by reason of engagement of the spring directlyagainst the :tace of" the guide portions 14. ln the preferred embodiment or' the invention sair` space-engaging-incase on the shoe is provided by direct use oit the spring 31. As shown in Fig ures l and', the portion oit the spring. arranged to engage the guide portions let is bent to provide an outward transverse offset 37 which will readily enter the spaces 36 when moved opposite same. disposedin one of such spaces and forcibly held against the adjacent ends of adjoining portions il, considerable resistance will be provided against displacement of the sash.V

Release of the spring from engagen'ient in a space may be effected by impressing a sudden but vigorous torce against. one olf the sine stiles 39 et the sash. After the sash has been moved suiiiciently to cause at least partial dise'f'igagement ot the spring with the space7 continued movement thereof will be comparatively tree and easy. ltwill be readily undorst-ood that by accelerating the movementot the sa l th A will not have eppoik tuaity are ely engage in the spaces and no appreciable resistance to the movement of y the sash will be caused.

lilith the offset thus ionsi wit-hout undue stiffness inthe operation of the sash, and without the use of manually operatable fastening means. 4
